OverClocked ReMix has finished its community-wide remix of Final Fantasy IV, and is offering the massive album free either whole or dissected, track-by-track.
Over 36 people collaborated to produce 46 arrangements of Nobuo Uematsu's highly-regarded score. The tone has changed to rock-opera as a result, says the OC ReMix website, although there are a range of other styles stuffed in.
There aren't many reasons not to sample a track or two, then - not least because Final Fantasy IV was released on DS recently and a sequel produced for WiiWare.
